Sounders and Beacons are important components of any Fire Alarm System, required by both BS 5839 and by enforcing authorities. While Smoke and Heat detectors are designed to sense the telltale signs of a fire, appropriately positioned Sounders and Beacons will warn building occupants to the danger and allowing them to escape. Wireless Sounders and Beacons provide increased flexibility due to not needing expensive and time-consuming cabling works to commission or install.
